Andesitic igneous rock.
Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.
The three families of igneous rocks are basaltic (mafic), andesitic (intermediate), and granitic (felsic). These families are classified based on their silica content and mineral composition, which in turn influence their color, density, and overall characteristics.
Igneous rocks containing mostly plagioclase feldspar and a significant percentage of dark silicate minerals are typically classified as basaltic rocks. These rocks have a composition that is intermediate between mafic and felsic rocks, with a silica content of around 50-60%. Basaltic rocks often form from the solidification of magma with a basaltic composition.
Andesite is a type of extrusive igneous rock with moderate levels of silica. Andesitic is an adjective used to describe volcanic material with the composition of andesite. For example, andesitic lava will cool to form andesite.
Copper is commonly found in igneous and sedimentary rocks, typically associated with areas of volcanic activity or hydrothermal deposits. It can also be found in some metamorphic rocks that have undergone mineral alterations.
Yes, andesitic rock is indeed an igneous rock that has a composition situated between basaltic and granitic rocks. It typically contains a moderate amount of silica, ranging from about 57% to 63%, which gives it characteristics that are intermediate between the two. Andesitic rocks are commonly found in volcanic arcs and are often associated with subduction zones.
granitic igneous rocks are light colored because of a lower density than basaltic rocks
Basalt is an igneous rock with very fine grains. It is dark colored. Granite is a variety of colors: gray, pink, and white. It has coarse grains.
Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.

Copper is commonly found in igneous and sedimentary rocks, typically associated with areas of volcanic activity or hydrothermal deposits. It can also be found in some metamorphic rocks that have undergone mineral alterations.
For igneous rocks,the composition depends on the source magma,either basaltic or granitic,For Sedimentary rocks it depends on source of sediments or nature of salts which existed in the basin from which precipitation took place, and for metamorphic rocks it depends upon the source rock.
Both are classified as igneous rock.
